This tab shows the assets that are in your Local Library, a local path that was set during setup.
Click an asset to add it to the top of the layer stack. You can also drag and drop an asset to the layer stack in a specific position.
On the left sidebar, you can search for an asset or apply filter to search a specific type. On the top, you can control how assets are sorted and change size of the thumbnails. You can also apply filters by selecting anyone of these from the drop down.
By right clicking an asset, you can remove it from the local library or you can view it in the folder containing the asset on your drive.
Change the view of your local library by selecting any option from the drop down shown at the top right of the local library.
